froth floatation process of sulphide ore

  • How Do We Separate Two Sulphide Ores By Froth

    For the separation of two sulphide ores the proportion in which oil and water are taken should be adjusted This can also be done by using depressants such as NaCN If an ore contains ZnS and PbS then NaCN is added during the process ZnS forms a complex with NaCN preventing it from coming into froth
